Thanks guys, all great info.
MIKEAA, I've always wanted to attend an S spree. I think Dayton is only about a 4 hour drive (one way). That's not too bad. I think that's where the Air Force museum is and I've been there before.
As of now, I'm leaning toward DC power with DCC (eventually) with hi-rail wheels (easier for me to see when putting cars on the tracks).
Again, THANKS to everyone.
Rick
